PURPOSE: To produce the compositions having excellent tensile, flexural, compression and adhesion strengths and are useful for adhesive agents or the like by reacting specific vicinal polyepoxide with specific curing agent.
CONSTITUTION: (A) A 1.8 epoxy equivalent vicinal polyepoxide is subjected to a reaction with (I) a diol such as polypropylene glycol or the like, (ii) one or more alkylene oxide such as ethylene oxide or the like and (iii) an epoxy resin intermediate such as an epoxy derivative of bisphenol-A or the like at a ratio wherein the ratio of hydroxyl functional value: intermediate epoxy resin equivalent amount is at least 2:1 and also under a condition so arranged that the intermediate epoxy resin is internally added in the longitudinal direction of polyol chains making it possible to obtain polyols of improved properties having 2,000 to 5,000 molecular wt. The obtained improved polyols are aminated and then reacted with a curing agent with amino group terminals thereby obtaining the object compositions.
